She said: "I’m not torn about whether to leave acting for directing. I want to go into directing. I am giving acting up to concentrate on working behind the camera.

“I’ll do one or two more films as an actress. Every once in a while I get a story like this and I’m so happy I get to play this role. I’ve loved acting, but I like arriving on set in jeans without having to do hair and makeup and being a part of the family.

“Being the director you are much more part of the big picture and I love it.”
